I recently purchased a Surf Champ (Gottlieb 1976) and when I got it home, I realized the plug was shot. I was going to simply replace the plug, but when I cut the wire, I realized there were just two black-coated wires and a green one in the middle. (See photos)

Both the black wires were smooth - so there was no way to tell which one was "hot" and which on was "neutral." (I supposed the "hot" goes to the copper-colored screw, and the "neutral" to the silver-colored screw, but I'd have to dissect the plug to figure out which wire went to which screw, and even then, I'd have to assume whoever wired this did it properly.)

So I've decided to replace the entire cord. Only problem is, I'm a relative newbie and have never done it. Yes, I've read Vids posts on replacing the plug, line, etc. but want to make sure I am doing this correctly, so I don't kill the game or myself.

(Question: The cord "appears" to be original, as it is part of the wiring harness bundle. Are these the kind of plugs Gottlieb sent out with the game in 1976?)

So I'll purchase a new cord that has black / white / green wiring. Two questions:

1. Can someone confirm that the transformer is currently wired correctly, according to the schematic?

2. If so, then I want to duplicate it with the new cord, correct? So the black wire goes to the fuse (yellow circle); the white wire goes to the "normal" tap bottom (white circle) and the green wire goes to the transformer ground (green circle).

Thanks in advance for your help!

Thanks! Do you know if that is standard issue cord for Gottlieb games of that era? Flat cord with both hot and neutral being the same color?

Also, any issues I should know about soldering what will be the new white/neutral wire to the transformer? A friend said it's best to avoid heat on the transformer - not sure why...

Gotcha. And with new cords, the "hot" is typically black and the "neutral" is white, correct?

Thanks for your help, both of you! Much appreciated.

Thanks, guys!

Rusbikeskilee, since you used to own a Surfer, can you confirm that the wire/plug shown in the photos above was the one which came with the game? That had two black wires and a green ground in between them? Since the power cord is bundled with the other wires in the wire harness, I assumed it came with the game. Not that it matters at this point, just curious since this is my first Gottlieb.

Thanks! And sorry for the misspelling on your handle.

Thanks, everyone!
